I noticed red stems at points of stress. Just below topping and adjacent to my LST pipe cleaners. I suspect others have seen this many times. But it's new to me.
Red fan leaf stems below topping

Totally normal for petioles to get a suntan from your lighting. Those leaves look green and healthy.
Many strains do that, as @zigzagman1960 said, no problem!
I’m just concerned about the tinsel growth on that puppy… 
I'm more concerned about the tiny white dots that are showing on some of those older fan leaves.
Red petioles aren’t usually a problem unless you’ve got other issues showing. They’re more used to confirm a problem than to diagnose one. If everything else is healthy and happy it’s likely genetics. I can see other colored petioles in the image that aren’t at points of stress (physical stress won’t cause red petioles), and overall I don’t see any other indicators of deficiency.
When your stem starts striping red then you’re likely looking at a K flag, however like @SmokingWings said, those white dots are interesting. Is it dusty where you’re growing?

Good catch, I didn't see them! Yes, those are concerning! Get a good loop or microscope and check the undersides of the leaves for potential spider mites. The upside is, if you've got em, you're still in veg, so you have more options than if you were in flower.

I think it is from my foliar spray that had aloe powder in it. It wipes off easy and it is actually light brown when inspecting. It is very similar to the powder I put in my foliar. But I am certainly no expert and do not know exactly what white mildew looks like in person

The underside looks clean to me

I saw those too but look at the second pic of the first post—undersides looking stellar! Probably water spots or overspray.
If all those small white dots wipe off with a damp cloth then not a problem.
It is not mildew but insects that I was thinking of. And, if it is insects then Spider Mites would be the first suspicion and concern.
Thing is, at this stage, they are almost impossible to see without using a decently powered loupe or microscope. Eventually they will be larger and then some of the adults can be seen on the top or bottom of the leaf fingers without any magnifying tool.
And once that is all taken care of we can get to the "tinsel growth" that @013 is understandably concern about.
